How Pirates Of The Caribbean Hijacked America’s Metric System

If the United States were more like the rest of the world, a McDonald’s Quarter Pounder might be known as the McDonald’s 113-Grammer, John Henry’s 9-pound hammer would be 4.08 kilograms, and any 800-pound gorillas in the room would likely weigh 362 kilos. NPR explores: One reason this country never adopted the metric system might be pirates. Here’s what happened: In 1793, the brand new United States of America needed a standard measuring system because the states were using a hodgepodge of systems. “For example, in New York, they were using Dutch systems, and in New England, they were using English systems, ” says Keith Martin, of the research library at the National Institute of Standards and Technology. This made interstate commerce difficult. The secretary of state at the time was Thomas Jefferson. Jefferson knew about a new French system and thought it was just what America needed. He wrote to his pals in France, and the French sent a scientist named Joseph Dombey off to Jefferson carrying a small copper cylinder with a little handle on top. It was about 3 inches tall and about the same wide. This object was intended to be a standard for weighing things, part of a weights and measure system being developed in France, now known as the metric system. The object’s weight was 1 kilogram. Crossing the Atlantic, Dombey ran into a giant storm. “It blew his ship quite far south into the Caribbean Sea, ” says Martin. And you know who was lurking in Caribbean waters in the late 1700s? Pirates. Read more of this story at Slashdot.

New standard sets baseline for HDR on PC displays

As video enthusiasts will tell you, just saying a display is capable of high dynamic range doesn’t say much — you need to know how well it handles HDR. And that’s crucial for PC monitors , where the accuracy and intensity of the picture can make all the difference when you’re playing a game or editing video. The team at VESA wants to do something about it. They’ve unveiled an open standard, DisplayHDR, that sets the baseline levels for HDR quality on PC screens. There are three tiers, each determined by the maximum brightness. DisplayHDR 400 is aimed more at laptops, where power and size tend to limit what’s possible. A monitor meeting this spec has to reach a brightness of 400 nits, offer true 8-bit color (at 95 percent of the BT.709 gamut), provide global display dimming and support the HDR10 format. That may not sound like much, but it’s 50 percent brighter than typical laptops, many of which ‘cheat’ to get 8-bit color through dithering. DisplayHDR 600 ramps up the brightness to 600 nits while requiring improved black levels and 99 percent BT.709 color accuracy (plus 90 percent of DCI-P3). The most advanced monitors can aim for DisplayHDR 1000, which supplies at least 1, 000 nits and even deeper blacks. The spec is limited to LCD monitors for now, although there are hopes to adapt it to OLED displays and other technology. And you won’t have to wait long to see it in use — VESA is promising DisplayHDR-rated products at CES in January. This doesn’t guarantee that you’ll be blown away by a Netflix movie or an HDR-enabled game, but it should discourage companies from pulling a fast one by slapping an HDR label on a display that doesn’t do the technology justice. Also, it could improve the adoption of HDR among your preferred hardware makers. If they know what to shoot for, they may be more likely to add HDR support instead of holding back out of uncertainty.

Whole lotta onions: Number of Tor hidden sites spikes—along with paranoia

Two sudden leaps in the number of advertised “hidden services” on Tor have led to rampant speculation about the cause of them. (credit: The Tor Project ) In recent weeks, the number of “hidden services”—usually Web servers and other Internet services accessible by a “.onion” address on the Tor anonymizing network—has risen dramatically. After experiencing an earlier spike in February, the number of hidden services tracked by Tor spiked to 114,000 onion addresses on March 1. They then dropped just as quickly, falling to just below 70,000 hidden services seen by Tor on Thursday—still twice the number that Tor had held steady at for most of 2015. “We don’t know what’s causing this,” said Kate Krauss, the director of communications and public policy for the Tor Project. “But it’s not difficult for even one person—a researcher, for instance—to create a lot of new onion addresses—which is not the same as actual websites or services. In fact, we want the process of creating onion addresses to be as easy as possible to encourage the creation of more onion services. These spikes are typically temporary—and as you see from the chart, this one is already going away.” Still, there has never been this sort of wild gyration in their number in recent times—or at least as far back as the Tor Project has kept metric data. So what caused the sudden near-tripling of the size of Tor’s hidden Web and its rapid contraction? Based on a deeper look at Tor’s metrics and discussions with both Tor developers and security experts, the huge spike in the “size” of the hidden Web within Tor was likely caused by a perfect storm of coincidences: major Internet censorship events in at least two countries, the relatively rapid adoption of a new messaging tool, a malware explosion, and ongoing attempts to undermine the privacy of the network.

Plunging Battery Prices Expected To Spur Renewable Energy Adoption

Lucas123 writes: Lithium-ion (Li-on) and flow battery prices are expected to drop by as much as 60% by 2020, making them far more affordable for storing power from distributed renewable energy systems, such as wind and solar, according to a recent report by Australia’s Renewable Energy Agency (ARENA). The 130-page report (PDF) shows that Li-on batteries will drop from $550 per kilowatt hour (kWh) in 2014 to $200 per kWh by 2020; and flow battery prices will drop from $680 per kWh to $350 per kWh during the same time. Flow batteries and Li-ion batteries work well with intermittent energy sources such as solar panels and wind turbines because of their ability to be idle for long periods without losing a charge. Both battery technologies offer unique advantages in that they can easily be scaled to suit many applications and have high cycle efficiency, the ARENA report noted. Li-ion batteries more easily suit consumer market. Flow batteries, which are less adaptable for consumer use because they’re typically too large, scale more easily because all that’s needed to grow storage capacity is more electrolyte liquid; the hardware remains the same.

Latin America Exhausts IPv4 Addresses

An anonymous reader writes “LACNIC, the regional Internet registry for Latin America and the Caribbean, considers its IPv4 address pool exhausted, because it is down to less than a quarter of an /8, roughly 4 million IPv4 addresses which are reserved for facilitating transitioning mechanisms. Half of those addresses will be assigned on a first come, first served basis, but no more than 1024 addresses per organization every 6 six months. Allocations from the last 2 million addresses will be a maximum of 1024 addresses total per organization. To maintain connectivity, it is now indispensable to make the switch to IPv6. LACNIC’s CEO expressed his concern that many operators and companies still haven’t taken the steps needed to duly address this circumstance. The RIRs for Asia-Pacific, Europe and North America have all imposed similar limitations on IPv4 assignments when they also crossed their local exhaustion thresholds. As of now, only AfriNIC is not in address exhaustion mode.” Joining North America, and Europe/the Middle East/Central Asia. Read more of this story at Slashdot.

This Obsidian Mirror Was Once Toxic Chemical Waste

There are plenty of ways to deal with chemical waste: You could ship it across the ocean . Or pump in into Ohio . Or, you could use plasma gasification—a Back to the Future -style process that “recreates the conditions inside a volcano” to incinerate waste. One byproduct of the process? A glassy synthetic obsidian. Read more…

UK Home Office Clarifies Rules Against 3D Printed Guns

The UK Home Office has clarified the rules against 3D printed guns, finally stating unequivocally that 3D-printed firearms are prohibited under the Firearms Act 1968. According to an informational release, it is an “offence for an individual to possess, purchase or acquire any component part of a firearm without a certificate.” 3D printed guns have yet to be officially criminalized in the US but it is increasingly harder to find and download the plans to the first 3D-printed gun, the Liberator from Defense Distributed. In fact, this original zip-gun style 3D model has been eclipsed by a real, fireable pistol made entirely out of metal and 3D printed using laser sintering . Regardless, the average consumer is miles away from being able to print a real gun at home, but that hasn’t stopped the UK authorities from fully outlawing the practice. The release states: [blockquote]The manufacture, purchase, sale and possession of 3D printed firearms, ammunition or their component parts is fully captured by the provisions in section 57(1) of the Firearms Act 1968. The definition of firearm in the Act includes any component parts. 3D printed firearms are subject to strict control in the following respects: a. under section 1 of the 1968 Act, it is an offence for an individual to possess, purchase or acquire any component part of a firearm without a certificate; b. under section 3 of the 1968 Act, it is an offence for a person to manufacture or possess for sale a component part of a firearm acting by way of trade or business; and c. under section 5 of the 1968 Act, it is an offence for a person to manufacture, possess, purchase, sell, transfer or acquire a component part of a prohibited weapon without the authority of the Secretary of State for the Home Department or by Scottish Ministers in Scotland. [/blockquote] Considering the possible threat from 3D printed guns is approximately zero, it’s brave of the UK Home Office to get out in front of the problem. In fact I’d wager that the moment 3D metal sintering becomes an amateur pursuit we will have far more societal problems to deal with than 3D-printed pop guns. via 3Ders

Apple’s iPad Air Cost-To-Build Estimated At Less Than iPad 3 At Launch

Apple has released its iPad Air, and while we don’t yet know how many it sold during opening weekend (it’s likely waiting to reveal launch numbers until the iPad mini with Retina display goes on sale), we do know that it seems to be enjoying strong adoption rates. The cost of building this latest iPad should help Apple’s product margins, too, if a teardown by analyst firm IHS iSuppli (via AllThingsD ) is any indication. IHS regularly makes a point of trying to backwards engineer the cost of building a brand-new Apple device by tearing them down and looking at what goes into one. This year, it estimates that Apple’s iPad Air runs between $274 and $361, for the $499 16GB Wi-Fi only model at the low end, and the $929 128GB Wi-Fi + LTE version at the top. As usual, margins are higher the further up the chain you go, but what’s remarkable about this device is that it actually costs an estimated $40 or so less than the third-generation iPad did  (IHS didn’t revise its figures for the fourth-generation iPad release) when it first launched, at every price point and model. That’s despite featuring a much more expensive display and touchscreen assembly that combines some layers to result in a a thinner overall package. Measurement for the touchscreen assembly is now at 1.8 mm, which is down from 2.23 mm on previous versions. There are savings in other areas, however, since the display requires fewer LED units (36 vs. 84 before) to power the screen, and that’s mostly because apart from the screen, many of the components are held over from older versions. The A7 is actually cheaper than the A5 was back in March when the iPad 3 launched, and the cellular array used in the iPad covers all LTE frequencies in the U.S., which means cheaper manufacturing costs overall since it only needs to make one version. Apple eking out more margin on the iPad Air could result in huge upside for it going into a busy holiday season, especially if numbers prove as strong as early evidence suggests they could be. The iPad mini, too, might enjoy a boost to profit for Apple, given that it also uses the A7 and appears to share a lot of componentry in common both with the full-sized iPad Air and with its predecessor.
